Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair cosmetic composition which is not removed after being attached to hair, and a method for imparting dullness and smoothness to hair using the hair cosmetic composition.

[0002]

2. Description of the Related Art There have been known various hair cosmetics which give a shiny or shiny feeling to hair by using various moisturizing agents in addition to fats and oils, silicones, etc., but a dull feeling (matte feeling) to the hair has been known. There is no known method for imparting a cosmetic or its cosmetics.

On the other hand, powder components are known as cosmetic bases for cleaning skin and hair. However,
Although these compositions are intended solely to keep the human body clean, they are rather disadvantageous in appearance, such as white spots on the skin. Therefore, after achieving the purpose as a detergent, it is necessary to remove the detergent adsorbing fat and sweat from the viewpoint of hygiene and aesthetics. That is, there has been no report on a hair cosmetic in which a hair component is applied without removing the powder component after the powder component is attached to the hair.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to provide a hair cosmetic which is not removed after being attached to the hair, for the purpose of imparting a dull feeling (matte feeling) and a smooth feeling to the hair, and An object of the present invention is to provide a method for imparting a dull feeling (matte feeling) and a smooth feeling to hair by using the above hair cosmetic.

[0005]

Means for Solving the Problems The inventors of the present invention have conducted intensive studies in order to solve the above-mentioned problems, and as a result, by using a hair cosmetic containing a specific powder, a sufficient feeling of dullness (mat) Feeling) and smooth feeling,
The inventors have found that the hair can be aesthetically and attractively fixed without damaging the hair, and completed the invention.

That is, according to the present invention, a hair cosmetic composition which is hardly soluble in water and contains at least one kind of powder at room temperature and which is not removed after being attached to the hair, and the above hair cosmetic composition The present invention provides a method for imparting a dull feeling and a smooth feeling to the hair, characterized in that the powder component is not removed after the material is attached to the hair.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail. The hair cosmetic composition of the present invention is characterized by containing one or more components which are hardly soluble in water and are powder at room temperature (hereinafter referred to as powder as a main component), and are not removed after being attached to the hair. The hair is straightened. By using the hair cosmetic of the present invention, a dull feeling and a smooth feeling can be imparted to the hair.

The powder as the main component used in the present invention is hardly soluble in water and can maintain the shape of the powder at room temperature, but is also powder at room temperature to 50 ° C. or lower. It is more preferable that the melting point of the powder is higher. If the powder composition cannot be maintained at room temperature or higher, the powder composition may be deteriorated when placed in an environment above room temperature, such as in direct sunlight with the powder composition applied to the hair. Because there is. The specific gravity, color tone, adhesion to the hair and chargeability of the powder, and the degree of dryness are not particularly limited, but those having a relatively low specific gravity are preferred, and those having a high dryness and low tackiness are preferred.

The average particle size of the powder as the main component used in the present invention is 0.01 to 1000 μm, preferably 0.05 to 700 μm, more preferably 0.1 to 700 μm.
μm. If the particle size is less than 0.01 μm, a dull feeling cannot be obtained, and if the particle size is more than 1000 μm, it becomes difficult to attach and hold the hair, so a dull feeling (matte feeling) is obtained.
In addition, the smooth feeling cannot be maintained, and the effect is aesthetically low.

The powder as the main component may be used alone or in combination of two or more. The amount of the powder is 0.01 to 90% by weight, preferably 0.1 to 80% by weight, more preferably 1 to 70% by weight based on the total weight of the hair cosmetic.
% By weight. If the compounding amount of the powder is less than 0.01% by weight, it becomes necessary to supply a large amount of the hair cosmetic to the hair, which is not practical. On the other hand, when the amount of the powder exceeds 90% by weight, the powder is difficult to be uniformly attached to the hair, the dispersibility of the powder in the hair cosmetic is inferior, and aggregation tends to occur during storage. . The amount of the powder as the main component in the hair cosmetic is 30 to 100% by weight, preferably 50 to 50% by weight, based on the nonvolatile components in the cosmetic.
-100% by weight, more preferably 70-100% by weight
It is. If the amount is less than 30% by weight, the influence of other components becomes large, and it is difficult to achieve the initial purpose.

The powder as a main component used in the present invention may be an inorganic substance or an organic substance. Specific examples of inorganic substances include silicon dioxide, silicic acid, magnesium silicate, calcium silicate, aluminum silicate, barium silicate, strontium silicate, diatomaceous earth, talc, sericite, mica, kaolin, montmorillonite, clay, bentonite, Vermiculite, titanium oxide film mica (titanium mica), bismuth oxychloride, boric acid nitride, zirconium oxide, zinc oxide, titanium oxide, lower titanium oxide, metal tungstate, hydroxyapatite, aluminum oxide, calcium sulfate, barium sulfate, Examples include magnesium sulfate, calcium carbonate, magnesium carbonate, calcium carbonate, magnesium carbonate and the like. Specific examples of organic substances include cereal powders such as flour and rice flour, natural products such as various starches, and chemically modified starches such as octenyl succinate starch ester metal salts and the like, and other chemically synthesized products such as silicone powders. Can be

The starch in the octenyl succinic acid starch ester metal salt may be corn, potato, tapioca, sago, rice, wheat, waxy maize, sweet potato, kudzu, etc., as long as it becomes a powder at ordinary temperature after chemical modification, especially corn. Starch is preferred. The metal salt may be any of calcium, barium, aluminum, iron, etc., as long as it is a powder that is hardly soluble in water, but aluminum is particularly preferable. Accordingly, among the above powders, octenylsuccinic acid corn starch ester aluminum is most preferable, and this substance is disclosed in U.S. Pat. No. 2,613,206 and JP-A-9-1943.
41, JP-A-10-158138 and JP-A-10-158139.

The shape of the auxiliary inorganic powder is preferably such that the particles have irregularities, and the average particle diameter thereof is 0.1 to
It is preferable to select one having a range of 1000 μm and an average particle diameter larger than the powder as the main component. If the particle size is smaller than 0.1 μm, the effect of redispersion / restoration is reduced, and if it is 1000 μm or more, smoothness is impaired. The compounding amount of the auxiliary inorganic powder is 0.01 to 20% by weight, preferably 0.1 to 10% by weight, particularly preferably 0.2 to 5% by weight, based on the total weight of the hair cosmetic.
% By weight.

As the auxiliary inorganic powder, silicon dioxide is most preferable, and the average particle diameter is in the range of 1 to 100 μm.
It is most preferable to select a powder larger than the average particle diameter of the powder as the main component.
